Blocks— DO Function Block
Description
Data Type: 102
Process variable of the DO block in AUTO and RCAS
mode, and is the value specified by the
operator/engineer in MAN and LO. In case of BAD
status the valve goes to the position specified in
ACTUATOR_ACTION.
Data Type: Unsigned8
Data Type: Unsigned8
Indicates validity of VALUE.
Data Type: 102
Actual position of the device.
Data Type: Unsigned8
Data Type: Unsigned8
Indicates validity of VALUE.
Data Type: 102
Target setpoint and status provided by a supervisory
host in RCAS mode.
Data Type: Unsigned8
Data Type: Unsigned8
Indicates validity of VALUE.
Data Type: Unsigned16
Defines which transducer parameter provides input
to the DO READBACK_D parameter.
Data Type: Unsigned8
Indicates whether SP_D should be logically inverted
before writing to OUT_D in AUTO or RCAS mode.
Data Type: Float
Time in seconds from detection of failure of the
actual used setpoint (SP_D=BAD or RCAS_IN
_D<>GOOD) to the action of the block if the
condition still exists.
A comm timeout changes the status of the
transmitted setpoint to BAD.
Data Type: Unsigned8
Defines the reaction of the device if a failure of the
actual used setpoint is still detected after
FSAFE_TIME or if the status of actual used setpoint is
Initiate Fail Safe.
Data Type: Unsigned8
Setpoint used if FSAFE_TYPE = 0 and FSAFE is
activated
